The monomers that react together to form polyurethane polymer are diisocyanate and diol.

<h3>What are polymers?</h3>

Polymers are a class of natural or synthetic substances
It is made up of small units called monomers arranged in a repeated pattern to form large molecules called macromolecules
Cellulose and resins are examples of natural polymers
Polyethylene and polychloroprene are examples of synthetic polymers.

Polyurethane polymer is made up of monomers diisocyanate and diol. It is mostly used in home furnishing in flexible form. The structures of monomers are as follows:

I don't understand this I'm confused

skad [1K]

Explanation:

Sodium, or Na, is 57.47% of the composition,

Hydrogen, or H, is 2.520% of the composition,

and Oxygen, or O, is 40.001% of the composition.

This is because mass% = mass/total mass x 100%.

2. For every 1 mole of C6H12O6, you need 6 moles of water. Multiply the 5.2 moles you are trying to make by the 6 moles of water you need, and you will need 31.2 moles.

3. x = 7.2 x 4 / 2 = 14.4 mol

The fuel used in many disposable lighters is liquid butane, C4H10

Charra [1.4K]

Answer:

1.45 *10^23 atoms C

Explanation:

3.50 g butane * 1 mol butane/58.1 g butane =0.06024 mol butane

in 1 mol C4H10 -------- 4 mol C

in 0.06024 mol C4H10 -------- 4*0.6024 = 0.241 mol C

0.241 mol C * 6.02*10^23 atoms C/1 mol C = 1.45 *10^23 atoms C

how does resistance change with temperature? is there more resistance or less resistance at higher temperatures?

timofeeve [1]

The resistance has a linear relationship with temperature because it increases as temperatures increases.

<h3>What is temperature?</h3>

Temperature refers to the activity (motion or thermal energy) in the atoms that form molecules.

The resistance of an electric conductor increases as the temperature increases since the thermal energy of subatomic electrons also increases.

In conclusion, the resistance has a linear relationship with temperature because it increases as temperatures increases.
